PATENT FFME.

ENAMEL-WARE PROTECTOR.

Application led April 24, 1922. Serial No. 556,347.

To all whom t may concern.

Be it known that I, ALBERT E. PLOYER, a citizen of the United States,residing'at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Enamel-Ware Protectors, of which thefollowing is a specification containing a full,`

clear, and exact description, reference being had to the accompanyingdrawing, forming a art hereof.

y invention consists in the novel construction hereinafter particularlydescribed and distinctly claimed.

The object of my invention is toprovide an improved means for protecting.the enamel-coating of enamel-ware or graniteware, to reinforce thesaine, and prevent chipping or breaking of said enamel during the use ofsaid ware; whereby it will be more durable and eliicient, and yet thecost will be low.

In the drawings,

Fig. l is a side-elevation of an enamelware handled-cup, having myinvention applied thereto.

Fig. 2 is a vertical section of the same, taken on the line 2 2 of Fig.1.

Fig. 3 is a view of the bottom of the same, and

Fig. 4 is a side-elevation of a handled stew-pan or similarenameled-ware cookingutensil, having my invention applied thereto.

The numeral l designates the sheetsteel or` metallic body of the vesselor utensil, to the exterior of which is applied, in the wellknownmanner, a coating of enamel or vitreous material 2, and to the interiorof which body is applied also a like vitreous or frangible coating 3.

The numeral -4 designates a reinforcement and protector for the saidenamel or vitreous coating, applied thereto in the present illustrationof my invention, iii the form of a rin of copper, which is substantiallyL-shape in cross-section, and forced upon the base or lower end of theveel or utensil, so that said ring will be held in place by frictionalcontact with the external coating 2 of said cup or utensil, and actthereon as a reinforcement to, and as a protection for, the said enamelor vitreous coatings.

Said metallic reinforcement 4 also acts as' a reinforcement andprotection to the interior enamel or coating 3, as well as to the saidexternal coating 2, by preventing the chipping or breaking-olf of theexternal coating 1n spots, and the consequent rusting orcorrosion oftheexposed spots thus deprived of an external protecting coating of enamel.

Said exposed spots of the metallic body 1 of the vessel, soon become sothin that they will be easily dented by accidental contact with hardobjects during use, and this dentmg will break the internal coating 3,and permit internal rusting and corrosion. which will quickly result inholes in the vessel, and its consequent leaking and worthlessness.

The particular advantages of the metal copper are that it iscomparatively soft, and acts as a cushion, preventing disagreeable noisewhich would occur if the protecting-ring were made of a harder metal andthe vessel carrying it were thrown recklessly or violently into contactwith the top of the range or stove; copper being also one of the bestknown conductors of heat, will rapidly conduct the heat of the lire tothe protected vessel; and this is true especially because thecomparatively soft copper ring acts as a sort of gasket, and makes atight lit between the stove or range to and the vessel which carriesvsaid copper ring, thereby enabling the heat to pass more readily fromthe hot stove-top," or from the exposed fire, to the said vessel.

The lower corner of enameled-ware vessels is usually rounded, and Iconsequently make the corner of my copper reinforcement rounded as at 5,to fit said rounded corners of the vessels.

The numerals 6 and 7 respectively, designate the handles of the vesselsshown.

I claim l. Thecombination of a vessel enameled on the outside, and aprotecting-ring of copper, arranged around the lower portion of thevessel, and having an annular integral portion extending inwardly underthe bottom of the vessel.

2. The combination of a Vessel enameled on the outside and inside, and aprotecting- 5 ring of copper arranged around the lower portion of thevessel, and having an annular integral portion extending inwardly underthe bottom of the vessel.

n testimony whereof, have signed my name to this specification inpresence of 10 tW'o subscribing w1tnesse`.

ALBERT E. PLO YER.
